TO. ALL WHQM 1T MAY CONCERN:

Be it known that I, THOMAS HALL, of Bergen, Hudson county, State of NewJersey, have invented 'a new :ind useful Improvement in Connecting-Rodsfor Machinery-g and I do hereby declare that thevfollowing is a. full,clem', und vexact description of the construction and operation ofV thesame, reference hcing'had to the unnexed drawings, marking :L part ofthis specifc'\tien. v 4

This invention is designed to obviato the owections to connecting-rodsused in runningsewing machines,

and for similar purposes, so that the wear ofthe parts nt the bearingscan be taken up orj adjusted, und the ends of' the rod be kept properlyfitted withy little attention or skill.

Figure 1, in drawing, is a, view of the connecting-rod complete, as whenin use.

Figure 2 is :i view of the end piece; and

Figure 3 is the end of the rod which fits into piece B, fig.l 2.

The same letters refer to like parts in eneh figure. v g

The rod is shaped at ends so ns to form one side of the bearing, asshown :it f.' The opposite side of hearing is formed in piece B at e.The parts are adjusted by the piece A sliding into piece 'B throughopening h L, shown in fig. 2, to enclose bearing S, :Ls in 'ig. `1. Theparts are secured in place by screw 0,' passing through slot d, in pieceB, into piece A, the head of screw C resting on the wedge-shtipedsurface W, holding piece B firmly when set, and e'ectunlly Ipreventingit from slippingl by reason ofthe inclined surface W.

I claim us my invention, und desire` to secure by Letters Putent- A lThecombinntion of the rod A, the sliding pieccvB, with wedge-shapedbearing, and screw C, when the seme are nrrang'edan'd operatesubstantially as described` v THOS HALL Witnesses:
